French authorities discovered this morning someone had defaced the tomb of iconic French author Alexander Dumas, located inside the Panthéon, in the city of Paris. The police was called in early in the morning after a janitor, doing his pre-opening rounds, spotted the graffiti on the tomb of the beloved author.

Authorities are still trying to determine who could have defaced the monument, as well as trying to ponder the meaning of the message left behind and of the strange sigil found alongside the words (click for larger image):

The message reads, “Dumas, We felt bored with the land, so we went into the sky,” and was “signed” by d’Artagnan and the Musketeers.

“Clearly we seek a deranged fan whose hold on reality is tenous at best,” said Inspecteur Clouseau, who has been assigned to investigate the case.

A young man interviewed at the scene told reporters he knew the meaning of the sigil, saying it was the logo for an upcoming jeux de rôle (roleplaying game) called Swashbucklers of the Seven Skies. Attempts to reach game creator Chad Underkoffler at his home in suburban Maryland, USA, were unsuccessful, as calls kept reaching a recorded message saying, “the robot needs beer to power up.”

News crews will continue to monitor the situation.
